Match the following terms and definitions. 1.breeding of individuals that have genes for two different characteristics codominan
Luden [163]
<span>Answers;
1.Breeding of individuals that have genes for two different characteristics; Dihybrid cross
2.A grid system used to predict possible combinations of genes due to random fertilization; Punnet square
3 A condition in which both alleles are dominant; Codominance
4.when more than two alternatives exist for a gene; multiple alleles
5.A condition in which neither pair of alleles is dominant or recessive, so the traits blend in the phenotype ;Incomplete dominance;

Explanation;
</span>Dihybrid cross;
<span>It involves the breeding of individuals that have genes for two different characteristics. It involves the cross of individuals that are both heterozygous for two different traits. For example two different traits in a pea plant; color and shape; for color we have; Y-allele for yellow seeds and y- allele for green seeds, For Shape trait; R-allele for round seeds and r-allele for wrinkled seeds. So the dihydbrid cross would be (RrYy </span>× RrYy). 
<span>
Punnet square;

</span><span>This a grid system or a square diagram that is used to predict possible combinations of genes due to random fertilization. It is used by biologists determine the probability of an offspring having a particular genotype. 
</span><span>The letters on the outside of a Punnett Square stand for the parent allele.
</span>
Codominance
;
<span>This is a condition in heterozygotes in which both members of an allelic pair are dominant and both contribute to the phenotype. 
A good example of codominance is the ABO blood group; A person with blood group AB, it means that both the A allele and B allele are equally expressed. 

Multiple alleles

</span><span>This is when more than two alternatives for a gene exist.
Examples of multiple allelism in human;The genes of the ABO blood group system. The human ABO system is controled by three alleles, namely; A-allele, B-allele and O-allele.

Incomplete dominance;
</span><span>This is condition in heterozygotes in which both members of an allelic pair are neither dominant nor recessive to other alleles, so the two traits blend in the phenotype of the individual. 
An example; is a snapdragon flower that is pink as a result of cross-pollination between a red flower and a white flower. Which means neither the white allele or the red allele are dominant. </span>

When would be a good time in San Francisco to collect seashells? Explain your answer.
snow_tiger [21]

Answer:

12th May at 4.17 PM

Explanation:

This is because this is during the low tides and the low tide is at its lowest, at -0.7, m than any other date or time of the month. This means that most of the shoreline has receded deep into the ocean and exposed most of the continental shelf than any other time. This leaves rooms for more sea shells to be exposed and easily collected.

Control and experimental groups. They repeated their experiment several times and found the results were the same.
Ira Lisetskai [31]

Answer: Experience 1 is the one that has the greatest reliability.

Explanation:    Because of this potential variation, biological experiments need to have a large sample size and preferably be repeated several times.  With more samples and repeating the experiment more often, the probability of arriving at a wrong conclusion due to random variation is diminished. As experience 1 has had several repetitions, it is the experience with a more reliable result.
